In applied mechanics, bending (also known as flexure) characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element.
The structural element is assumed to be such that at least one of its dimensions is a small fraction, typically 1/10 or less, of the other two. When the length is considerably longer than the width and the thickness, the element is called a beam. For example, a closet rod sagging under the weight of clothes on clothes hangers is an example of a beam experiencing bending. On the other hand, a shell is a structure of any geometric form where the length and the width are of the same order of magnitude but the thickness of the structure (known as the 'wall') is considerably smaller. A large diameter, but thin-walled, short tube supported at its ends and loaded laterally is an example of a shell experiencing bending.
In the absence of a qualifier, the term bending is ambiguous because bending can occur locally in all objects. Therefore, to make the usage of the term more precise, engineers refer to a specific object such as; the bending of rods, the bending of beams, the bending of plates, the bending of shells and so on.
i have a circular tube of diameter 20mm,thickness 1mm and length 500 metres
i bend the tube into a radius of 50mm. obviously the tube has entered the plastic stage. But what would have happened to the material properties.

Light always wants to travel in a straight line, however, the space is curved around massive objects such as black holes, so it would seem as if the light was being bent as it traveled around the black hole. The space around the Earth is curved.. so satellies traveling along parallel paths can...
Hi, this may seem like a really easy simple question, but I've not yet managed to figure it out. Yesterday I was looking through the encarta and I came across 'Relativity' so I started reading about it, on one of the demos it said;
'When Sara is standing still in space she switches on a torch...

"What we know. The force of gravity is much greater here on the face of the Earth opposed to the far upper atmosphere of our planet. Yet it is around a planet that we typically observe and associate with the bending of light. Here on the face of the Earth it...
If i have a simply supported J Section beam, when I'm calculating the max deflection, what value of I do i use?
I have already had to calculate Ix, Iy and Ixy.
I would imagine that as deflection occurs along the y-axis that i would use Iy.
Or do i use Imin? I have already calculated...
The equivalence principle (EP) - which is the basis of general relativity – states that you cannot distinguish between an object’s behaviour in a uniform gravitational field from that in a uniformly accelerating frame.
If light travels vertically in a gravity field it loses or gains energy, and...
Hi,
I need to work out the bending moment of a steel tube, 25mm diameter (3mm thick) 410mm long.
im assuming i have to use youngs modulus in some way? what's the correct formula for working out when it will bend?
thanks
chris

In a table of different steel qualities the information about a perticular type of steel can be as follows:
Steel type:
S235
Tension/Pressure:
0\pm60
130\pm130
Bending:
0\pm190
150\pm150
My question is, what do these values tell me? The values are in N/mm^2
How can concentrations of mass (such as the Earth) or energy bend space and time? I mean, is there any theory that states what causes space-time to be bent by these large masses? Aren't space and time just abstract concepts, so how can they be bend?
Is a well studied problem. I am a textiles engineer and am doing some work on modelling the interaction of the yarn with a brush ring (circular brush with hairs slowing the yarn down). You can easily calculate the deformation of a hair caused by a force perpendicular to the curve of the hair in...
i know that gravity can bend light so from this principle i have two theoretical questions. first, can light bend around an object to the extent that the object becomes invisible? basically what i am thinking is that a beam of light coming form behind it will bend around the side and exit the...
In the terms of rotational inertia why is it hard to walk without bending your knees?
The greater the bulk of the object mass to its axis the greater its rotational inertia.
how can I relate that to walking without bending knees?
I understand that with rotational inertia an object...
